Answer:
0.675 m/s
Step-by-step explanation:
Let height of shadow= y,CD=x
Height of man=2 m
Speed of man=
Therefore,
Differentiate w.r.t t
When the man is 4 m from the building
Then, we have x=12-4=8 m
Substitute the values in above equation then, we get
Substitute the values then we get
Hence, the length of his shadow on the building decreasing at the rate 0.675 m/s.
Given:
The expression is:
To find:
The difference.
Solution:
We have,
It can be rewritten as:
Taking LCM, we get
Therefore, the value of the difference is .
|-1/5| < |-1/3| < |-7|
Your answer:
B. y = -1/5 x^2; y = -1/3 x^2; y = -7x^2
Look at the picture.
